Guy across the street just rang my doorbell and handed me two boxes of sealed tapes and turned around and walked back home. He's an IT guy at a police station. Pretty sure these are for dictation. Probably not much for music. Still kind of cool to get free **** because he knows I collect boomers.
The clear bodies were found on the older cassettes. Later, Maxell changed to a black body. The black body version supposedly has better tape stock, but I wouldn't know for sure. I think I still have a couple of sealed, clear bodies. Keep that neighbor happy.
